#APACHE HTTP CLIENT HOW TO#
We learned how to send a POST request with Authorization, how to post using HttpClient fluent API, and how to upload a file and track its progress. HttpClient = HttpClients.custom().setConnectionManager(connectionManager). In this article, we illustrated the most common ways to send POST HTTP Requests with the Apache HttpClient 4. HttpRequestRetryHandler retryHandler = new StandardHttpRequestRetryHandler() Retry processor ,StandardHttpRequestRetryHandler RequestConfig requestConfig = RequestConfig.custom() setSocketTimeout： The timeout period for waiting for the response from the opposite end after the request is issued reference: If the Keep-Alive header is not present in the response, HttpClient assumes the connection can be kept alive indefinitely. setConnectionRequestTimeout： The waiting timeout for getting connections from the connection pool setConnectTimeout： Set the connection timeout You can set a separate number of connection pools for each domain nameĬtMaxPerRoute(new HttpRoute(new HttpHost("xx.xx.xx.xx")), 80) PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager() Private static CloseableHttpClient httpClient = null
Import .conn.PoolingHttpClientConnectionManager Import .client.StandardHttpRequestRetryHandler Ĭode tool class ： package com.zh.boot.utils You can create its object by instantiating the BasicCredentialsProvider class, the default implementation of this interface. The CredentialsProvider Interface maintains a collection to hold the user login credentials. There are three kinds of ：httpclient、resttemplate、feign, Next, make a record of each kind of processing process. Step 1 - Create a CredentialsProvider object. Why there are three kinds ？ No strict requirements were made at the initial stage of the project, As a result, everyone uses their own habitual way to complete the function. Used in the project http Call mode, There are three kinds of. Didn't do it before, Because the timeliness requirement is not very strict But now the emphasis is on timeliness, It needs to be adjusted as a whole.
#APACHE HTTP CLIENT SOFTWARE#
These licenses help us achieve our goal of providing reliable and long-lived software products through collaborative, open-source. There are many external projects in recent project development http call, Because our interfaces have corresponding timeliness requirements, So we need to use for the project http Call to transform the connection pool. The Apache Software Foundation uses various licenses to distribute software and documentation, and to accept regular contributions from individuals and corporations and larger grants of existing software products.
